Issam Khedri, 29, eldest brother of cigarette vendor Adel Khedri, leans on a traffic sign in the Tunisian capital, Sunday, April 14, 2013 in Tunis. Adel set himself on fire on March 12, 2013 outside the Municipal Theater in the heart of the capital. One of his last words to a doctor at the burn center was "faddit" - slang for "fed up." The self-immolation comes more than two years after another Tunisian high school dropout-turned-street vendor, Mohamed Bouazizi, set himself on fire and launched mass protests that eventually toppled dictators in four Arab countries.

Issam Khedri, 29, eldest brother of cigarette vendor Adel Khedri, holds a newspaper which printed a photo of his brother, Adel, moments after his self-immolation outside the capital's Municipal Theater, in his room in Mellassine slum of Tunis, Tunisia on Sunday, April 14, 2013. A month after Adel's death, five of the 20 beds at the Ben Arous burn center in Tunis were filled by people who had set themselves on fire. Self-immolations make up about 25 percent of admissions, while the rest are accidents, according to Dr. Amen Allah Messaadi, the center's trauma chief. Some of those setting themselves on fire suffer from mental problems, but most are just like Adel - unemployed high-school dropouts in their 20s. Such acts are not common among college graduates, he says. (AP Photo/Ons Abid)

Nepalese policemen rush as a Tibetan monk burns after he set himself on fire in Katmandu, Nepal, Wednesday, Feb. 13, 2013.

The dramatic protest marked the 101st time since 2009 that a Tibetan monk, nun or layperson has set themselves on fire, according to officials from the Tibetan exile government, based in India. The protesters are calling for Beijing to allow greater religious freedom and the return from exile of their spiritual leader, the Dalai Lama, who lives in India. (AP Photo)
